User blog comment:Dante-Must-Die-Mode/What The Heaven And Hell?: Nero/@comment-26222858-20150330153518

Almost every comment here makes no sense.

First off, Why are you talking about Trish? She's not Nero's mother, and there is no theory that says this, so why is she mentioned?

Next, if Nero has the blood of Sparda, that already states that he is related to Dante and Vergil.

Now then, lets talk about Nero and Yamato. Nero was able to, without even meaning to, repair the Yamato and retrieve the power from it, with which Agnus could not. That would mean that the sword Yamato (and probably Rebellion) only are applicable by the relatives of Sparda. So even though the sword itself is older than Sparda, the sword was made specifically for Sparda and his offspring, so it really doesn't matter how old this sword is.
